70 degrees F, 70%RH for everything?

[lazi]

I'm at the planning stage of a project that has recirculating air through 2 grow boxes and a similar sized 'lung space', each grow box is 4' x 3' and has a 600w hps running 12/12. One light on while the other is off. The extra 6 hours for vegging provided by cfls.

The lung space will also be used for drying. 1 fan recirculates the air and another is used for extraction. Still a lot of details to work out but want to make sure it's workable should I manage to build it.

First question should be will it work OK with the same air traveling across plants that are lights on, lights off and drying? Can't think of why they shouldn't but I might have missed something.

Assuming it's OK, what temps and humidity do I go for?

This post gave me the idea of 70'F/70%RH

I did try drying as close as I could get to 70'F/70%RH on that advice, great results.

So will 70'F/70%RH work for everything?

If not, what temps and humidity would you suggest?

I would keep the RH between 40 and 45, less chances of molds then.

yes continual air movement is a must. secondly it sounds neat. keep your temps closer to the 77F mark and the humidity as the previous post. build a small screen rack to dry on with warm air circulating above and below. spread the bud in a single layer on the screen. if heat is an issue, then you can mount horizontal and air tube with ducting straight thru. use a black poly flap at the split made of strips.
